Abstract

There is provided an electronic detonator with electronic delayer, comprising: - a conductive shell comprising - an open end for receiving elements such as an explosive charge, and - a closed end, and - a printed circuit board (PCB) comprising the electronic circuit of the delayer, the printed circuit board being placed inside the conductive shell, characterized in that the electronic detonator further comprises at least a resilient, compressible and conductive gasket - positioned by the open end in a space defined by the PCB and an inner surface of the conductive shell, - filling at least part of the space between the PCB and the inner surface of the conductive shell, such that protection against electromagnetic interferences (EMI) is allowed and - contacting the ground connection of the PCB and the inner surface of the conductive shell such that acts as connection path for grounding the PCB, allowing protection against electro-static interference (ESD).
